ABOUT ME

iOS developer

I have created over 100 iOS apps and 10+ MacOS apps, some of them also awarded in UK and Greece. I usually work with JSON APIs and also very challenging UIs that need a lot of custom controls. Have implemeted apps using frameworks for bluetooth, contacts, camera, video edit/encoding, image edit, CoreData, push notifications, location service, messaging, share to social media, stream of audio and others. I also have and support lots of open source GitHub and CocoaPods projects.
I am a fun of C,C++ and arduino, too.
